Follow these steps:
First : Save your important files and data of your mobile .
Second : type the code below on the mobile screen :
*2767*3855# and wait until the operation is finished.
After this operation ...all errors and problems in mobile will be fixed.

there is nothing wrong with your screen, the problem is
from the flex that connects your screen to the phone's main board. This
flex must have worn out that's why your screen is not displaying any
picture.

The problem is common with flip and slide phones. The
flex gets worn out as a result of constant opening and close of the flip
or slide phone.

I would urge you to replace the flex and I am
assuring you that your screen will display picture again. You might also
be lucky to find out that the flex is not well fix, that is, it may
have loosed contact.

If you cannot change the flex yourself,
maybe you should take the phone to a local repairer within your
vicinity, so that the flex can be fixed/replaced.

It all depends on what type of phone you have, and I don't mean which brand. If you phones is a GSM technology phone the it requires a SIM card to work, all of your contacts should be already saved in your SIM card. The same goes for the messages. All of this is possible only if you had save all your contacts and messages in your SIM card, but if you saved your contacts and your messages in your phone, and your phone don't power on, then you lost it. Try the SIM card in another phone that uses the very same band as your old phone, and check in the phonebook, if it shows empty, then all your contacts were saved in the phone.

Install and use Samsung PCStudio 3.2. (download it from samsung mobile web site). You can save everything in your phone to you PC using it software. It is not necesary to see the phone screen to do that. Hope it help.
